Patent CA-2144408-C (CA)
Inventor: HARMAN ROBERT KEITH
IPC: G08B13/24

Abstract: In an intrusion detection system comprising an open transmission line (10), for example a "leaky cable", and a receiver un-it (12S, 12T, 145, .14T, 16) for processing a radio frequency signal received by the line to detect perturbations caused by an intrud-er (28), problems of nonlinear sensitivity due to line attenuation are resolved by combining perturbation signals (R S, R T) from both ends of the open transmission line. A processor unit (18) computes logarithmic values of the perturbation signals from the opposite ends of the line and combines them to detect presence of an intruder. The sum of the logarithmic values may be used to determine presence of the intruder and the difference between them may be used to determine the location of the in-truder relative to the end of the line. The processor may also use phase information from the two perturbation signals to fa-cilitate detection in the presence of multipath effects. Reference signals (LO, IF T, RF) and power may be transmitted be-tween receiver units (12S, 145, 12T, 14T, 16) by way of the open transmission line (10) itself. The system may employ several transmissions having different frequencies, in which case the processor (18) will sum perturbation signals for all trans-mission frequencies for each end of the line, combine the two sums, and compare the result with a predetermined threshold

Inventor: MURATA HIDEYUKI
IPC: H05B33/10
Filed: 1995-09-13
Granted: 2000-03-07
Abstract: According to the present invention, in a first aspect thereof, an organic electroluminescent device having an electroluminescent layer and/or a charge injecting/transporting layer formed out of a thin film of organic polymers of network structure which are excellent in heat resistance and durability, e.g., polyoxadiazoles is obtained by conducting a vapor deposition polymerization of a bifunctional monomer, a polyfunctional monomer of 3 or higher in functionality or a mixture of the polyfunctional monomer and bifunctional monomer and heating the resultant polymer in vacuum or an inert gas. In another aspect, an organic electroluminescent device having an electroluminescent layer and/or a charge injecting/transporting layer formed out of a thin film of polyoxadiazoles is produced without the formation of hydrogen halides (acids) as by-products by performing a vapor deposition polymerization of a monomer having two carboxylic acid halide groups and a monomer having two silylated carbohydrazide groups and heating the resultant polymer in vacuum or an inert gas.

Title: Well test imaging
Inventor: SLEVINSKY BRUCE A
IPC: E21B47/00
Filed: 1996-08-12
Granted: 2001-09-18
Abstract: An improved method is provided for establishing the location and orientation of the boundaries surrounding a reservoir and creating an image thereof. A conventional well test is performed on a well, establishing measures of the well's pressure response as a function of the rate of pressure change in the reservoir over time. Conventional techniques may be used to determine measures of the radius of investigation. A plurality of radii of investigation are determined as a function of time. A calculated response for an infinite and radially extending well are the measured response are compared as a ratio. Variation of the ratio from unity is indicative of the presence of a boundary at that radius of investigation and the magnitude of its effect related to an angle-of-view. Each radius of investigation is deemed analogous to a ring. Reservoir encompassed by this ring is in communication with the well. This ring is interrupted along its circumference by an encounter with a boundary or boundaries, the arc length of such an interruption being equal to the angle-of-view. The remaining arc of the ring is rotated so that at least one of the arc's end-points coincides, or is fitted, with a known geologic feature. Should the same ring arc intersect another feature, the ring arc is cut to form a new arc end-point. The remaining arc is rotated so that its new end-point again coincides with a geologic feature. Once all the ring arcs for each radius of investigation are fitted, their collective end-points form an image of the periphery of the reservoir.
